Archaeologists brush soil away from skeletons lying twisted in an open grave, some wearing decayed leather boots, in a cypress-lined municipal cemetery in central Spain. The grave is one of more than 2,000 mass burial sites estimated to lie across Spain dating from the 1936 to 1939 civil war and the ensuing dictatorship of General Francisco Franco. Only a handful have been dug up and documented. Eighty years after the start of the conflict, a bloody ideological struggle between left and right, authorities are backing efforts to recuperate some of the more than 100,000 victims forcibly 'disappeared' during that time.
